We are all nothing but a bunch of shifting tendencies. Tendencies are shaped by the force of habit. None of us have to definitely have a certain thing (or do a certain thing) even though we might feel the urge to do so to be strong. Our tendencies are often our desires without Wisdom or evaluation. Not following may leave us hollow in a certain sense. This feeling of hollowness is caused by our attachment to that tendency as being part of our illusionary self. The recognition of our tendencies lead us to the dissolution of our false self. Not following our tendencies blindly is spiritual cultivation. The next time you feel like having or doing something, be it a neutral or ill thing, resist for a while, and let your Wisdom evaluate its worth before following it-Does the tendency lead towards Enlightenment or to more suffering?
